  // - Lay out each keyboard in rows of sub-arrays.  Each sub-array
  //   represents one key.
  // 
  // - Each sub-array consists of four slots described as follows:
  //     example: ["a", "A", "\u00e1", "\u00c1"]
  //
  //          a) Normal character
  //          A) Character + Shift or Caps
  //     \u00e1) Character + Alt or AltGr
  //     \u00c1) Character + Shift or Caps + Alt or AltGr
  //
  //   You may include sub-arrays which are fewer than four slots.  In
  //   these cases, the missing slots will be blanked when the
  //   corresponding modifier key (Shift or AltGr) is pressed.
  //
  // - If the second slot of a sub-array matches one of the following
  //   strings:
  //       "Tab", "Caps", "Shift", "Enter", "Bksp", "Alt" OR "AltGr"
  //   then the function of the key will be the following,
  //   respectively:
  //     - Insert a tab
  //     - Toggle Caps Lock (technically a Shift Lock)
  //     - Next entered character will be the shifted character
  //     - Insert a newline (textarea), or close the keyboard
  //     - Delete the previous character
  //     - Next entered character will be the alternate character
  //
  //   The first slot of this sub-array will be the text to display on
  //   the corresponding key.  This allows for easy localisation of key
  //   names.
  //
  // - Layout dead keys (diacritic + letter) should be added as arrays
  //   of two item arrays with hash keys equal to the diacritic.  See
  //   the "this.VKI_deadkey" object below the layout definitions. In
  //   each two item child array, the second item is what the diacritic
  //   would change the first item to.
  //
  // - To disable dead keys for a layout, simply assign true to the
  //   this.VKI_layoutDDK (DDK = disable dead keys) object of the same
  //   name as the layout.  See the Numpad layout below for an example.
  //
  // - Note that any characters beyond the normal ASCII set should be
  //   entered in escaped Unicode format.  (eg \u00a3 = Pound symbol)
  //   You can find Unicode values for characters here:
  //     http://unicode.org/charts/
  //
  // - To remove a keyboard, just delete it, or comment it out of the
  //   source code
